What is a Service Load per ASCE 7-16 1

[NBRY1]

I interpret the definition in ASCE 7 for 'service loads' to indicate that they apply solely to the serviceability state (e.g., settlement) and not the ultimate limit state (e.g., bearing capacity) in geotechnical design. Is my interpretation correct?

SERVICE LOADS: Loads imparted on a building or other structure because of (1) self-weight and superimposed dead load, (2) live loads assumed to be present during normal occupancy or use of the building or other structure, (3) environmental loads
that are expected to occur during the defined service life of a building or other structure, and (4) self-straining forces and effects. Service live loads and environmental loads for aparticular limit state are permitted to be less than the design loads specified in the standard. Service loads shall be identified for
each serviceability state being investigated.

Historically, bearing pressures have often been defined at a service-level, particularly when bearing capacity is controlled by allowable settlement.

Over the past decade, more geotechnical design is being performed at an ultimate limit state. So this may or may not be the case for your bearing pressure check. You'll have to read the report to see what was intended.

Service load includes dead, live and environmental loads to be expected. Factored load includes service load multiplied by an appropriate load factor.

Pls Look to the definition again ;
(SERVICE LOADS: ...... Service loads shall be identified for each serviceability state being investigated. )


Serviceability considerations are ; vertical deflection ,drift, settlement , vibration , expansion...

Pls have a look to see the combinations and load factors for serviceability under consideration:

I cannot give you the formula for success, but I can give you the formula for failure..It is: Try to please everybody.

My take isn't strictly per ASCE 7; however...

To me SERVICE loads are simply unfactored loads. The "real" loads, to my way of thinking.

I view SERVICABILITY as those conditions (other than member overstress) which could make the structure unsuitable for its intended purpose. Deflection, vibration, settlement, sway, permeability, etc.
